Patented July 25, 1933 PATENT JACOB THOBDSEIBLOF KON'NERN, GERM'ANYTIPPABLE AND PORTABLE MIXING APPARATUS Application filed. October 3,1931, Serial No. 566,695, and in Hungary May 21, 1931.

This invention relates to a tippable mixing apparatus, which is arrangedportable or stationary, especially for mixing quantities of mortar,concrete, road making maartificial manures and the like.

The invention consists in producing a constructionally simple device,cheap to make and adapted to withstand rough treatment,

and which facilitates the charging and mixing of the materials inquestion, such as cement sand or the like, and also dumping of thefinished mixed materials.

According to the invention the tippable frame of a stationary orportable mixing machine has two abutting pairs of bars bent at an angle,one pair of bars supporting the machine during the mixing, and the otherduring the emptying of the mixing vessel. This vessel is rotatablymounted around an axle extending from its bottom and mounted in abearing and preferably supported on rollers or the like.

Owing to this construction the machine can be tilted into two differentinclined positions, namely for mixing and for emptying the vessel.

For the purpose of facilitating intensive mixing, especially of muddymaterials and gravities, the mixing vessel is provided with a removableinsertion ring with mixing arms. Several embodiments of the inventionare illustrated by way of example in the accompanying drawing in which:

Fig. 1 shows the apparatus in side elevation in position fortransporting. 2 is a similar view showing paratus in position formixing.

Fig. 3 shows in side elevation the apparatus in position for dumping.

Fig. i is a side elevation of a stationary tippable apparatus. a

A frame is composed of two longitudinal beams 10 extended to formhandles 9 and supporting members 3, connected by suitable struts andtransverse members. A pivot pin 1 is mounted on the frame. On this pin 1the apsolid substances having different specific a mixing vessel 2 isrotatably mounted and provided with outwardly projecting handles 4. Inorder to relieve the pivot pin 1, the mixing vessel 2 is preferably alsomounted on rollers arranged on the frame. In the portable constructionan axle 8 and wheels 7 are fitted on the frame like a hand-cart, whereasin the stationary construction small wheels 3a may be arranged on thesupporting members.

For the purpose of obtaining intensive mixing of the materials it ispreferable, in the case of many materials, to provide the mixing vesselwith an insertion ring 12 carrying stirring arms 13. This arrangementenables a uniform mixing without subsequent separation of materials ofdiiferent specific gravities which have a tendency, when being mixedwithout an insertion ring, of partly separating, in that the lighter andcoarser materials roll to the top and the finer and heavier materialssink on to the bottom of the vessel. The struts or stirring arms,widened towards the upper end and fixed on the insertion ring, convey inupward direction the lighter material rolling forward during therotation of the mixing vessel. This material. then drops into the middleor on to the bottom of the mixing vessel.

The operation of the portable construction is as follows:

The mixing vessel 2 is transported in the position, shown in Fig. 1. Theframe is then brought into the position, shown in Fig. 2, after whichthe materials to be mixed are charged into the vessel, which is thenrotated by means of the handles 4. Owing to the rotation of the mixingvessel, the materials to be mixed are lifted in the vessel, where theyroll over, and consequently a falling, pouring and consequentlyintensive mixing movement is imparted to the materials.

When the mixing process is terminated,

the a ngaratus is returned into the position 9 illustrated in Fig. 1,and conveyed to the point of use. Here it is tipped into the position,shown in Fig. 3 so that the material can be emptied into receptacle 11by slightly turning the mixing vessel.

shape from the periphery of said vessel adapted to enable the rotationof said vessel by hand.

2. A tippable mixing apparatus as specified in claim 1, comprising incombination with the vessel, a ring loosely inserted in said Vessel anddownwardly projecting arms on said ring, bent towards the middle of thevessel adapted to intimately mix the contents of said vessel when saidvessel is rotated.
